A set of natural numbers multiples of 7 less than 100 is finite or not.
It is a finite set. Because there are finite numbers.
A set of natural numbers is finite or not.

State whether each of the following sets is a finite set or an infinite set:
(i) The set of multiples of 8.
(ii) The set of integers less than 10.
